Good points raised here. Arts and Culture are still mostly under the umbrella of the "Entertainment Industry". At the same time, art galleries and museums are not as much part of the same M.O. of operations and finances as Popular Music for example.
There should be grants? Absolutely. Some countries manage their grants very well, while some don't. The number of Asgardians ON SITE would also influence that. But for the whole structure to make any sense we would first need to know how the whole economy, services, jobs, etc would work once there are enough people off-planet.
Grants by themselves shouldn't be the expectation of any artist, artists always found their niches and even if not everyone can do it, they can manage to pay their bills if they find enough public for their work, and in a healthy economy, a safe environment and a place that encourages that, I imagine that would also work well.
There are millions of questions we need to ask ourselves about logistics we need to ask ourselves first AS A NATION, as a geographical place that does not even exist yet. A different number here and there could change everything. A ministry of culture is a must.
- But to go back to the focus of the question:
-Grants & Sponsorships
-Foundations and Institutes
- -Self-sustaining market
that is what we would expect from Culture handling in Asgardia. Not in that order.
